Add a sumo arena to lobby games. it would be a 1v1 game. Game time would be 5 minutes long and a 12 block wide circle as the platform. First to get knocked off loses. If time runs out, the closest to the edge will be the loser. When time gets to the last 10 seconds you get a stick with knockback one on it. Players would not take dmg (obviously) and you would get your fist until the last 1 seconds where you get the knockback stick. people would take normal knockback and you guys can do what you want with the map cuz i suck at architect stuff.
